Supreme Pharmacist System

Zhou Wen followed the experimental procedure and pipet the supernatant.

"Blowing" is an academic term, which means to use a test tube gun to extract the supernatant, and then blow it out. The purpose is to fully stir the supernatant in the test tube.

Pipette back and forth several times, then extract the two DNA samples into a centrifuge and start centrifuging.

After fifteen minutes the centrifugation was complete.

Extract the supernatant from group A to the side of the electrophoresis machine and add it from the gel well.

Cover the electrophoresis tank cover, select the electrophoresis voltage and direction, turn on the power switch, and start electrophoresis.

Then in group B, the supernatant was also extracted, added from the gel well of another electrophoresis machine, and electrophoresis was also run.

Then came the long wait.

The computer will compare the extracted DNA with the mouse genes in the "NCBI Gene Bank" in the United States one by one, and it will take at least 6 hours.

Because there are 2.5 billion DNA base pairs in the 20 pairs of chromosomes of the white mouse, it takes a long time.

During this time, you can read novels, watch dramas, and eat melon seeds.

But Zhou Wen didn't have time.

I went to catch a small white mouse, and first observed it with the eyes of true sight.

What he didn't expect was that what appeared in front of him this time was an introduction, [Rat Name: Little White Mouse, a variant of Mouse Mouse. Gender: female. Rat age: 11 months. 】

"Hey, why did you see this?" Zhou Wen turned his head to look at Lin Jiayi whose back was turned to him, and the scene he saw before appeared again before his eyes.

[Name: Lin Jiayi. Gender: Female. Age: 24. Occupation: Biology student. body condition:? ? ? Mental state: ? ? ? 】

He thought of the method of observing DNA, and his eyes narrowed slightly. Soon, the picture in front of him began to become clearer and clearer...

"Damn... Fuck, Fuck..."

In his eyes, the white lab coat on Lin Jiayi's upper body slowly turned into fibrous tissue, spreading and increasing... moving forward, it was a white chemical fiber fabric.

The pores of the chemical fiber fabric became thicker and thicker in front of my eyes, and finally passed through this layer of chemical fiber fabric and turned into a black cotton fabric.

Next is the epidermal keratinized layer, dermis, arteries, veins, hair follicles...

At this moment, Lin Jiayi suddenly turned around and asked, "Zhou Wen, what are you looking at?"

Zhou Wen who was interrupted, the picture in front of him disappeared, he recovered his senses, rubbed his nose and said, "Uh...you didn't look at me, how did you know I was looking at you?"

Lin Jiayi pointed to the stainless steel frame of the sterile operating table next to it, on which Zhou Wen's reflection could be clearly seen.

Lin Jiayi smiled and asked: "Hey Zhou Wen, you are so kind to help Shi Lei do experiments, so you can stay with me, right?"

Zhou Wen: "...how could you have such an unrealistic idea?"

Since Qu Fangfang left, Lin Jiayi probably felt that no one in the laboratory could threaten her appearance, so her speech became more and more unrestrained.

Of course, Lin Jiayi still looks pretty good, she needs to have a cheeky face, and a figure with a figure, and her white lab coat is stretched tight.

It's just the realistic group, all thinking about finding a tall, rich and handsome boyfriend.

And it's too calculating, which is a bit annoying.

Lin Jiayi smiled and said, "Hey~ It doesn't matter if you don't admit it... Forget it, let me tell you something, I already have a boyfriend, it's too late for you to chase after me now."

Zhou Wen turned around and cut off the little white mouse's neck, opened his stomach, and said with a smile: "Congratulations on getting out of the order. Tell me, what's the other party's situation?"

"He is also from our school, a year younger than me, a native of Jiangzhou, and he studies CS..."

While Lin Jiayi was talking, most of Zhou Wen's attention was on the mouse in his hand.

He found that when he extracted bone marrow from the thighs of white mice, he could already see the strands of DNA.

It was much easier now, and he could more intuitively see possible problems in the DNA extraction process.

He soon discovered that a large amount of DNA fragments was lost during washing with hypotonic fluid.

I don't know if it is caused by the low permeate concentration problem?

Fortunately, it does not affect the extraction of genes, and the concentration issue will be studied later.

Next is the counterweight centrifugation.

Zhou Wen's centrifugal test of one plant at a time.

Soon he found out the reason for the failure of group B extraction, which was a problem in the DNA extraction process.

This is a common problem for novices. Others, such as temperature control, time control, technique, etc., will affect the number of DNA strands extracted and the success rate.

Under normal circumstances, there is no way to do this. There is a difference between left-handed extraction and right-handed extraction. It may fail if the centrifugation is more than one second or less. A higher or lower temperature will also have a great impact.

Because DNA is invisible to the naked eye and cannot be touched, novices can only find out possible problems through experiments over and over again. That is often said to rely on "experience".

But now that Zhou Wen has the eye of true seeing, he can directly see the DNA, but the result is completely different.

He stepped over the process of accumulating experience and directly became a top expert...

...

Time passed quickly, and it was already half past five in the evening.

Lin Jiayi stood up and stretched, beat the back of her neck, walked to Zhou Wen and said, "Hey Zhou Wen, do you want to go eat together?"

Zhou Wen, who was "mixing glue", said without raising his head, "You go first, my side will be fine soon."

Lin Jiayi didn't notice that there was a layer of mouse corpses piled up in the waste bin next to her, she nodded and said, "Okay, then I'll go."

"Um……"

The electrophoresis analysis was not completed until 7:30 in the evening.

After comparison, it was found that the extraction of group A was successful, while the data of group B was as expected, and the data was seriously unreasonable, indicating that the extraction really failed.

Zhou Wen looked at the data chart, and the corner of his mouth couldn't help showing a smile.

The task required 6 gene fragments, and in the afternoon he extracted a total of 8 strains, of which 3 were obtained after electrophoresis analysis, 1 was obtained after electron microscope observation, and the other 4 were identified by naked eyes.

At this moment, a soft voice sounded in my ear, as nice as a voice actress.

[The mission conditions have been met, do you want to submit the mission immediately? 】

After Zhou Wen was stunned for a moment, he was overjoyed and immediately opened the pharmacist system.

On the blue attribute board, a prompt box popped up, which read [Do you want to submit the task now? whether】

Zhou Wen chooses 【Yes】

【Ding! mission completed. Rewards are being distributed now... Congratulations, you have obtained 100 subject experience points and 200 points. 】

After distributing the experience, a suggestion box popped up in front of me again, [Would you like to open the box now? whether】

Zhou Wen was slightly excited at first, but with the pop-up reminder of unpacking, he became excited.

"God bless, open a million... No, 10,000 will do. If it doesn't work, 1,000 will do."

He is really short of money now, and only 100 yuan is left in all his belongings.

Today is only March 19th, and the 100 yuan will last until the beginning of next month.

In fact, when he came to school a few years later, he had 2,000 yuan on him.

As a result, the mobile phone was accidentally broken, and I spent 1,000 yuan to find a third-hand 7P from my junior. Then I recharged the meal card for 600 yuan, bought some odds and ends, and only 100 yuan was left.

Zhou Wen prayed silently in his heart, and then chose [Yes]

Just after choosing, a black lacquered wooden textured treasure chest popped out in front of my eyes, with intricate patterns engraved on it, and an ancient key was suspended beside it.

"It's kind of like that~" Zhou Wen rubbed his hands excitedly, and then muttered in his mouth: "The Emperor Ou possesses his body, and the non-chief avoids..."

【open】

As the words fell, the key floating next to the treasure chest was automatically inserted into the keyhole of the treasure chest.

After turning around, the treasure chest slowly opened, and an object shining with white light emerged.

Before Zhou Wen could see what it was, a prompt box popped up in front of him.

He took a closer look, [Congratulations, you got a bio-type N99 mask × 10...]
